      Run an async servlet in jboss behind a web proxy such as nginx with proxy_buffering on (the default).
      Observe (by logging etc.) that the client browser does not receive the respose data for 1 minute after the server side asyncContext.complete().
      An iptables log confirms that async connections are held open for 1 minute after the response data was written, whereas non-async requests are closed immediately.

    Description

      Servlet 3.0 page call AsyncContext.complete() sometime after startAsync()
      The web request has no more input.
      The socket connection should be closed if KeepAlive is false, but it remains open for 60 more seconds.
      Code debugging indicates a bug on line 802 of org.apache.coyote.http11.Http11AprProcessor.java
      http://anonsvn.jboss.org/repos/jbossweb/tags/JBOSSWEB_7_0_3_FINAL/java/org/apache/coyote/http11/Http11AprProcessor.java
      It returns the socket close flag for unfinished requests instead of finished requests.
